This book provides a basic introduction for the student to hazardous materials chemistry. Coverage of chemistry, rather than non-chemical hazards, is particularly stressed on a level which the layman can understand. Basic terminology is emphasized at all levels, as are simple chemistry symbols, in order to provide the student with an introductory knowledge of the language of hazardous materials. Seventeen chapters cover: (1) an introduction to chemistry, atoms, elements, and the periodic table; (2) bonding in molecules and an introduction to inorganic chemistry; (3) an introduction to organic chemistry; (4) alkenes and alkynes; (5) alcohols; (6) ethers; (7) an introduction to the carbonyl functional group; (8) ketones and aldehydes; (9) carboxylic acids, esters, and amides; (10) nitriles and amines; (11) aromatic compounds; (12) flammable materials; (13) physical/chemical properties; (14) compressed gases; (15) corrosive materials; (16) two additional EPA hazard characteristics; and (17) toxicological properties. Department of Transportation definitions and classes of hazardous materials are appended. (LZ)
